Image capture devices for a secure industrial control system

A secure industrial control system, comprising:

• a communications/control module provisioned with a first unique security credential;
• an input/output module provisioned with a second unique security credential;
• a communications backplane that physically and communicatively couples the communications/control module to the input/output module;
• and
• an image capture device provisioned with a third unique security credential and comprising:
• an image sensor;
• a signal processor coupled to the image sensor;
• and
• a controller for managing the signal processor and transmitting data associated with processed image signals to at least one of the input/output module or the communications/control module via a communications interface that couples the controller to the at least one of the input/output module or the communications/control module,
• wherein the controller is configured to establish an encrypted tunnel between the controller and the at least one of the input/output module or the communications/control module based upon the third unique security credential of the image capture device and at least one of the first and second unique security credentials associated with the at least one of the input/output module or the communications/control module,
• wherein the image capture device is provisioned with the third unique security credential at a point of manufacture of the image capture device from a key management entity, and
• wherein the third unique security credential of the image capture device is at least one of modifiable or revocable by the at least one of the input/output module or the communications/control module.
